USA-Made Raised Duplex Receptacle Electric Outlet Covers for 4x4 Steel Electrical Boxes
These raised steel covers are designed specifically for standard duplex receptacles and are engineered to fit 4-inch square metal electrical boxes used in exposed-work installations. With crushed corners for a secure and precise fit on both drawn and welded 4x4 metal boxes, these covers allow the installer to mount a duplex outlet directly onto the raised cover while still providing ample space inside the box for wire splicing and connections.
Premium Duplex Outlet Covers for Exposed-Work Electrical Systems
This collection features USA-made raised steel covers designed to mount a traditional, NEMA-standard duplex receptacle on a 4x4 metal box. These are functional device-mounting covers—not blank plates—allowing electricians to mount a duplex outlet directly to the cover, which then attaches securely to the box for a clean, rigid, code-compliant installation.
Designed for 4x4 Metal Boxes
All covers here are engineered to fit:
- 4x4 drawn steel boxes
- 4x4 welded steel boxes
- 4-inch square junction boxes used with EMT, rigid, or MC conduit systems
The crushed corners ensure strong metal-to-metal seating, perfect alignment, and vibration-resistant stability—ideal for demanding commercial and industrial environments.
When Are Duplex Raised Covers Used?
Raised duplex covers are used whenever a standard duplex receptacle needs to be installed on a surface-mounted 4x4 metal electrical box. They create the correct raised depth and mounting configuration while still allowing the box to function as a junction point for wiring and splicing.
These covers are most commonly used in exposed-work applications, where electrical conduit is mounted on the surface of the wall instead of inside it. This is common in commercial, industrial, and utility settings.
Typical applications include:
- Garages and workshops where outlets must be surface-mounted
- Factories, warehouses, and industrial buildings
- Basements, boiler rooms, and mechanical spaces
- Workstations or equipment areas requiring accessible outlets
- Commercial EMT or rigid conduit runs where the outlet mounts directly to a 4x4 box
Instead of using a mud ring behind sheetrock, these covers allow the duplex outlet to be mounted directly on a steel raised cover. The cover then attaches to the 4x4 box, creating a durable, clean, code-compliant exposed-work installation commonly used by electricians, contractors, and facility maintenance teams.
